These spring loaded hand retractable plungers are used to prevent any change in locking position due to lateral force. Pulling up on the threaded end retracts the plunger pin into the body. The handle end is threaded for users to attach their own grip or for use with air cylinders, cables, etc. The body is made from steel with a black oxide finish. The plunger pin is ground and hardened. Supplied with a jam nut.
